Abstract
The invention relates to a cooling system for equipment and network cabinets and to a method for cooling such cabinets, together with the electronic modules located therein.In order to achieve with extremely simple means and particularly low capital and operating expenditure a high power cooling for densely packed cabinets and cabinet arrangements, particularly server cabinets in data processing centers and the like, an air ducting is provided in a substantially airtight cabinet with equally long airflow paths and therefore equal flow resistances, together with a uniform supply air temperature. The circulated airflow is cooled with the aid of an air-water heat exchanger in the lower cabinet area. The heated exhaust air is collected in a collecting duct with a rising flow, reversed and supplied in a falling flow to the heat exchanger.
